Abstract
In a heat exchanger for treating a flowable material, a multiplicity of disc elements are secured to and extend transversely of a shaft rotatably mounted within a casing. Disc elements are arranged in a number of planes extending transversely of the shaft and spaced apart in the axial direction. Material to be treated is introduced into the casing and is moved through it in the axial direction of the shaft by the disc elements and stirrer elements secured to the disc elements. The stirrer elements extend in the axial direction of the shaft and can be continuous for the extent of the disc elements or they can extend between adjacent disc elements or be supported by an individual one of the disc elements. In a preferred arrangement, the stirrer elements are bar-shaped and are located at the radially outer edges of the disc elements.
